l .ade vat the other face comes into joint vbearing relations with the joint-surfaces on the nozzle-boss F. When the parts are in this condition, which is shown in Fig. 5, not only is the fountain itself hermetically sealed, but a non-capillary joint is end of the nozzle, and the ink in the nozzle, in the feed-bar, and in the writing-pen is all occluded, protected, or prevented froni escaping or soiling the hands, clothing, or cdfntiguons articles.- This joint is formed between the cap P and the jointforming boss F on the nozzle and .is a noncapillary or hermetcal joint.

Since ink is likely to remain in the screwthreads of thenozzle and be transferred therefrom to the,.scre\vvthreads of thel secondary screw-oap P and to the interior of the secondary cap itself, it is desirable to wipe and clean the parts-that is to say, the screwthreads on each part-at least'externally before applyingihe secondary screw-cap Pto the nozzle Nin the manner shoWnjmFig. 5. This being done, thefonntain-,pen itself becomes a cleanly instrument throughout and is in little danger of soiling things with which it comes in contact, and the entire structure or safety fountain-pen may be used as a hermetically-sealed and portable ink stand or holder Without hesitation or danger.

. I claim as my invention- 1. In safety fountain-pens, a cap provided at its closed end with a safety screw-plug adapted to fit and close the open end of the reservoir hermetically and the reservoir in combination.

2. In safety fountain-pens, a cap providedat its closed end With a safety screvwplug adapted to fit and close the open end of thereservoir hermetically, in combination With the reservoir, and also providedwith a secondary cap adapted to fit and cover the safety- 5. In safety fountainfpens, a cap C pro. 4

vided with a screw safety-plug G and with 'the screw safety secondary cap P in combi` nation with the screwnozzle N and With the barrel or reservoir H. Y
